They are all 100 machined on all surfaces stress relieved and shotpeened.
H beam vs i beam connecting rods.
H beam rods are more difficult to machine so they are often more expensive.
H beam is a stronger design when bending stress is considered davis said.
Depending on the material you would want at least 900 inch of thickness in that area.
Consequently h beam connecting rods are often recommended for high torque motors that produce a lot of power at low rpm under 6 000 rpm.
With an h beam rod you should look at the thickness of the blades.
The ohio crankshaft h beam connecting rod is by far our most popular rod.
Some rod suppliers offer h beams as their entry level or less expensive line of performance rods and offer i beams for all of their high end racing applications.
Basically the h beam itself where the slot is cut out.
Conversely h beam connecting rods are a little bit stiffer and rigid and that makes them ideal for higher horsepower higher torque applications where there is going to be more compressive forces again this comparison only holds true if your comparing rods with the same material finish and length.
Ohio crank h beam rods.
All rods use arp 2000 bolts it is designed for durability with a little more material around the bolt.
